Embodiment 1
[0029] The distance between the 2D display screen and the gradient pinhole array is g=4mm. Both the micro image array and the gradient pinhole array contain 10×10 units, of which, there are 10 units in the horizontal direction and 10 units in the vertical direction. The micro image array The pitch of a single image element in the gradient pinhole array is p=4mm, and the pitch of a single pinhole in the gradient pinhole array is p=4mm. 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.8mm, 0.7mm, 0.6mm, 0.5mm, 0.4mm. by formula The calculated thicknesses of the pinholes in the 1st to 10th columns in the gradient pinhole array are 0.9mm, 1.1mm, 1.4mm, 1.7mm, 2mm, 2mm, 1.7mm, 1.4mm, 1.1mm, and 0.9mm, respectively.
[0030] In short, the integrated imaging 3D display device based on the gradient pinhole array has the same horizontal width of each column, and the same thickness of each column, and the horizontal width and thickness of the pinholes from the center of the integrated imaging 3D display...

The invention relates to the field of imaging, in particular to an integrated imaging 3D display device based on a gradient pinhole array. The device includes a 2D display screen and a gradient pinhole array; wherein the gradient pinhole array is placed in front of the 2D display screen, and the horizontal and vertical central axes of the gradient pinhole array are respectively aligned with the horizontal and vertical central axes of the 2D display screen; In the gradient pinhole array, the thickness of the pinholes in any column is the same, the horizontal aperture width of the pinholes in any column is the same, and the thickness and horizontal aperture width of the gradient pinhole array gradually increase from both sides to the middle; each image of the present invention The light emitted by the element can pass through the pinhole corresponding to the image element to form a normal 3D image, and the light emitted by the image element in other columns cannot pass through the pinhole, thereby eliminating the crosstalk in the horizontal direction, and has a wide range of applications in the field of 3D imaging. Value.
Description
technical field [0001] The invention relates to the field of imaging, in particular to the field of 3D imaging. Background technique [0002] The integrated imaging 3D display device uses the reversible principle of the optical path to record the stereoscopic information of the 3D scene on the image recording device through a pinhole array or a microlens array to generate a micro-image array, and then display the micro-image array on a 2D display screen. A stereoscopic image of the original 3D scene is reconstructed through a pinhole array or a microlens array. Compared with the integrated imaging 3D display device based on the microlens array, the integrated imaging 3D display device based on the pinhole array has the advantages of low cost, small weight, thin device thickness and no limitation of the manufacturing process. However, the optical efficiency of an integrated imaging 3D display device based on a pinhole array is significantly lower than that of a microlens arr...
